The use of high-throughput synthesis and purification in the preparation of a directed library of adrenergic agents.

A library of potential agonists and antagonists for adrenergic receptors was prepared using high-throughput solution-phase parallel synthesis. Traditional solution-phase reductive amination reactions followed by rapid purification by ion exchange chromatography yielded products with near-analytical purity. An array of ketones and amines, arranged in an 8 x 12 matrix, were combined to form 96 individual compounds.
